Using the services of "virtual private cloud", you pay for the amount of resources at your disposal. Once the resources are reserved, the payment for which is removed from the balance of each hour. It will be charged regardless of whether or not the resources are used. When calculating the maximum rate of payment is taken into account each resource per hour. If, for example, within an hour you repeatedly change the quota of the project, calculation of the payment will be calculated based on the maximum values.
In Control Panel, each project has a button "Optimize quota" - clicking on it, you will be able to bring the quota of the project in line with the resources consumed. Because of this you will never have to pay for resources that are not actually used.
System Resources: features payment
Processor Cores
You can rent any number of processor cores. Rentals are available only whole cores, up to 100% load. To avoid an unexpected lack of resources on each host reserved the required amount of CPU time. If you change the number of processor cores, the machine can be migrated to another host.
Memory
For each project, you can request any amount of memory in megabytes. Memory is reserved in full screen when creating virtual machines.
Disks
The cloud can be rented discs of two types: basic and quick.
A basic disk performance corresponds to SATA-drives enterprise-class. It is suitable for use in projects, for which do not require frequent reading and writing information.
Quick drive is a solution based on the SSD-drives. RTT and performance improved over the basic disk in several times.
Store images
We have already mentioned that in our store provided the opportunity to work with ready-made images of virtual machines. All images are placed in special storage. Its usage is charged in the same way as using a basic disk.
Floating IP-addresses
On the floating IP-address we mentioned in the previous article: inside a virtual machine, all ports are listening on the private ("gray") address, and the outside of the machine is available for the public ("white") address. This technology is well suited for light duty projects. Her undoubted advantage is flexibility: the floating IP-address can always be detached from the machine and attached one to the other.
Visitor Subnet
Service users' virtual private cloud "we are able to provide the public subnet of 5 (" white ") addresses in a separate VLAN. This method of access to the internet tested for years and seems to be more reliable. At the start, we offer five subnet addresses.
Windows license
If you plan to create virtual machines in the cloud running OC Windows, you do not need to purchase the license separately: we offer it for rent. The rental price includes and regular updates. Payment for the Windows license is charged at a fixed rate per hour.
Network Traffic
Each account is entitled to three free terabyte external traffic per month. According to preliminary calculations, this should be quite enough for most projects of small and medium-sized.
Once the limit is exceeded, with the balance of each hour will be written off funds for traffic - both inbound and outbound.
To optimize the traffic flow can be purchased in advance at a reduced price. This proposal should primarily be of interest to customers working with large volumes of data.
Balance VPC
When you create a new project or modify an existing quota of the project, a special counter in the control panel will show at what period should be enough available funds on the balance sheet. This will help you avoid unexpected shutdown of all servers due to a lack of funds on the balance sheet.
Conclusion
So, a new service launched - join and use. Please send us your questions, comments and suggestions for its further development and improvement.
Naturally, at the current level, we are not going to stay long. We have big plans for the development of VPC. In particular, in the near future there will be many additional services, new types of discs (even faster than those that are available now), rent load balancers, and more.
We also plan to continue the series of articles on the issue of VPC in our blog. Follow the news!
